TO ALL WHOM IT MAY CONCERN: v p

Be it known that-we, Faninnnren DEN/'amsn` and Jnoon MILLER, of Brooklyn, `Kings county, New York, have invented a new and useful Improvement in Mongers, Feed-Boxes, die.; and we dohercby declare that the fol-` lowing is a full, clear, and exact description thereof, which will enable others skilledin the art to `make and use the saine, reference being had to the accompanying drawings, forming part'of this Specification, in which-4- Figurc l'represents a front elevation, partly in section, of our invention. Figure 2 is a vertical cross-section of the same, theplane of section being Figure 3 is a plan or top view of the same.V Figure 4 is a detail vertical sectionalview of our improved feed-box, the plane of section` thereof being" indicated by the line y y, fig. 1 i i Similar letters of reference indicate corresponding parts. This invention relates to such a connection .of mangers, fe

indicated bythe une n, sg. 1.

ed-boxes, or feed-troughs with ordinaryfclock boxes or troughs have been filled, closed, and the clockwork arranged. p y v t The object of this invention is toeconomize time and labor, especially in large dairies, studs, and stal-iles,` and to provide regularityin the time of'feeding, the apparatus being so arranged that any desired numberof, i troughs or boxes will bc simultaneously opened from or by lneans of one clock-,work with which theyare connected.v u l i l l A represents a manger or -trough of `suitable construction. It is provided with a hinged cover, a, which is weighted in rear of its pivoting point, or which is connected with a Weight, b, thatis suspended from aplate orf1 lug that projects beyond the' pivot vc, by which the cover is hinged to the ends of the Vtrough ormamger.` This` i weight has the tendency to always. keep the cover a open, as is indicated by red lines` in iig. B is an elbowlever pivoted to or near o'ne end of the trough, and having a hook-shaped termination of ':niearm` The other` horizontal arm is connectcd'by a rod, d, with a bell-cranltlor lever, e, which `is pivoted tothe wall of the stahl as shown. The hell-crank e may be connected by means o i' any desired number of rods,ff, and intermittent bell-cranks, with a bell-cranlng, which is also pivotedv to the wall of the stable,` or `building with wliic `th Istable may-be connected, by the aforesaidwreds f, which connect the bellecranlgrs e andy. Gis a clock-work ordinary or suitable construction, on which a dial, L, which revolves with the hour-hand of the `eloclnas nary alarm attachments, is arranged. A cam-disk, t', which revolves with the dial t, being connected witlrthel same, and which has a notch or recess in its circumference, supports the end. of an 'elbow-lever, D, which is i l pivoted by means oi' a pinna', to the frame of the clock, or to some otherstationary device, DE is a stationary` i, l

vwith the cam t', when the dial 7L. will be stationary, and the hand will turn. A bell-crank, k, which carries a pin hand, which is fitted ont-he arbor around which the diai L turns. The hand F` can, if desired, be connected on one arm, and which is, by another hell-crank, Z, which is provided with a'pin for `moving the crank apressed so against the lower end of the vertical arm oi' the leveriD that it thereby presses the `hook-shaped end of thel f y horizontal arm of thc lever D upon the edge of the disk The pin on the horizontal arm of the crank l is, by the action of a spring, m, pressed upon the horizontal arm of the crank lc. To theupper partei' the ver-l tical arm of the crank Zis secured a pin, u, which fits underthe pin o, that is secured tothe free end cfa swinging bar, F, as shown. The iree'end of the bar F is provided with a weight, G, whichztends to pull it down` The bar F is lield'up by resting upon the pin n.. Byra wire or other rope, p, the bar F is connectedwith the bell-crank g, and thus a connection between the trough A and the clock-workis effected. l

The operation is simple and as follows: 'lhe 'end ci' thelever B, which has a heck-shaped termination, `is hooked over the cover L of the trough, so as-to hold it down.` Thcdial It is then turned, so that that hour at which itis desired the door a should he opened will stand opposite to the 4.haiid E. The parts are then all i ,i in the position shown in iig. l. -At the desired time the notch in the disk z' will come under the cud of thelev D, when 'the latter will, by the actioucf the spring m andwcight G, be thrown into the notch, the cran l and Zfollowing. The pin '1L will thus he moved from under the ,pin o, and the bar F will be pulled down by the weight G,'thereby pulling the rodp and crank g, rods f, "crank e, rod d, and lever B, and disengaging the latter from the cover c', so tliat'the same will be opend by means of the weight as is indicated byred liu'cs in l 1. The position of the bar F and its appendageg when the door is opened, is also shown by redlines in lig..1.

The disk con then be turned by turning n. cog-wheel, g, which meshes into a eoglwheel that is mounted on the saine sleeve on which the disk is mounted. When it is desired to open the bottom of zt feed-boit which isheld above the trough or manger, and which contains the oats or food, but which retains the same until the sax-id bottom .is opened,

when the contents Awill drop into the trough, we prefer to use the device which is shown partly by blue lines in iig. 1.

The feed-box H is inzide of any suitable shape and materiel, und has a, hingcdbottom, T, which een be openedby swinging down, a-s shown by red lines`in iig. 1. A catch, s, on this door, engages with u vibrating hook, t, which is fixed on n crank-Shaft, l, in thc inside of thebox H, said shaft being` connected by means of n. rod, u, with a bellcra-nli, v, 'which is, by nicnns of a. rod or rods, w, and intervening bell-cranks, connected with an arm projecting from a hinged weighted lever, J. The free (not weighted) end of thislever is held under a, pin, z, which projects from a. bell-crank, K,iwhich is connected by o. rod, L, with the bei'. Gr, and which is provided with n spring, a',

as shown. The operation is the same as described for the other apparatus. When the-lever D falls into the notch in the disk z', the lever G will fall and will pull the rod L, thereby drawing the pin z oft the lever J'. The

letter will then draw the rod or rods w, andwill thereby turn the crank-21 and reise the rod u. The shaft I will thereby be turned so tha-t the hookvwill be drawn may from the catch s, when the bottom will drop and the groin fall into the trough. This latter arrangement een be specially used where a number of feed-boxes o1'l managers nre t'o'be opened at once, the zipparatns leading to each manger being connected with the lever J in the saine manner as the rod w is connected with it.

- What we claim as new, und desire to secure by Letters Patent, is V 1. Connect-ing:r the trap-doors of mangers, feed-boxes, or troughs, with clock-work, in suche, manner that `the said doors can be simultaneously opened at any desired time, substantially as and for the purpose herein shown and described. 5

y2. The 'disk z', on the arbor ot' the clock-work C, in` combination with the levers D, c, Z, and F, the latter being connected with the door or `doors of the inanugers, troughs, or feed-boxes, substantially in the manner herein shown and described. e

The hinged bottom 7- of the feed-box H, in combination with the catch s and swinging hook t, the latter Abeing connected with the clock-work C, substuntinlly'ns herein shown und described.

4. The weighted cover a of the trough or manger A, in combination with the catch-lever B, which is connected with the clock-work C, substantially as and for the purpose herein shown and described.
